Can you use an iPhone to set the world text speed record?

I doubt anyone has a definitive answer on this, but I'd love to hear your opinion as well. Currently I can type the phrase “The razor-toothed piranhas of the genera Serrasalmus and Pygocentrus are the most ferocious freshwater fish in the world. In reality they seldom attack a human.” in under 30 seconds on my iPhone. The world record is around 42 seconds I believe. I need to know if I can attempt the world record with my iPhone, and I've asked Guinness but they take forever to get back to you.
